Even if you are a beginner you respond to what I've learned so far. With the tools, galletto, mpps etc) read the ecu, and also read the id that you d? the hardware and the software of the control units; at this point, if the tool you the law and you write it, you save the file, modify it with software type (Titanium) save it and the write.
If the tool instead does not read the ecu but the writes only, is able to? to read the id of the control unit and through this identify on the forum, the original file that you have not been able to read directly from the car, modify it as above, save it and the write.
If the ecu goes into the write lock, detaches and re-schedule in the BDM. In theory (very small) steps should be these.
